In 2007, Tuvalu was getting 2% of its energy from solar, through 400 small systems managed by the Tuvalu Solar Electric Co-operative Society. These were installed beginning in 1984 and, in the late 1990s, 34% of families in the outer islands had a PV system (which generally powered 1-3 lights and perhaps a few hours a day of radio use). Each of the eight islands had a medical center with a PV-powered vaccine refri.
